We have a 2016 Forest River Forester. Can't locate the drain for the fresh water tank. Found a blue hose under the unit that appears to be coming out of the FW tank but there is no valve to release the water. Any suggestions on where the release valve is?

The valve should be in a compartment immediately above the line that extends below the floor. There is a door inside that compartment open it and find a filter and the blue line should be to the right of the filter and a valve in the line.

Thanks for your replies. I found a compartment under the shower that has a small filter and a blue hose behind it but no valve and that appears to be above the FW tank, to high to drain the tank. I've gotten under the unit and can see a blue hose coming out of floor. There is not a cap or valve on that hose. It goes straight up in to the floor. I've looked in the outside compartments to see if the valves could be there. But nothing. The FW tank appears to be under the bed. The top of the tank is at floor level. With the slide out there is about 10 in between the bottom of the bed and what appears to be the top on the FW tank. So I can see the top of the tank and what must be the bottom from under the unit with the hose coming down. Where is the valve?

Post what model you have and you'll get the correct location I'm sure.
Here's the location on mine, 2701DS.

Sorry I didn't post the model. If is a 2016 Forester 2431S. Since my last post, I got under the unit again. The blue hose coming down from the FW tank had a bunch of foam insulation covering about 4 inches of the hose. I thought the drain valve is under the foam. Cut away the foam and could see about 6 or 8 inches up to the bottom of the tank. No valve. Still looking.

I would check the compartments on the driver's side rear where your bed is with the F/W tank. Someone will chime in soon with the location I'm sure.
Try running the water pump and listen in the compartments. That's where it should be.

I think the mystery of the FW drain has been solved. There isn't one. I called several RV service departments. All but one said they had no experience with a Forester 2431. They one that did said they had one in to be winterized and found no FW drain. They couldn't get in touch with anyone at the factory because they are closed this week so they used the pump to drain the tank so that is what I did.
